Rim Seal Foam Pourers

Rim Seal Foam Pourer is designed to discharge fully aspirated foam directly to the annular seal area of the open top floating roof storage tanks for fire or vapour suppression. Fully aspirated foam provides the most effective performance. HD rim seal foam pourer is UL Listed and FM Approved. The rim seal foam pourer design provides protection from the wind, allowing the aspirated foam to gently discharge onto the protected area of the floating roof tank. Gentle application minimizes submergence and agitation, increasing the effectiveness of the foam blanket. This design allows a uniform and cohesive foam flow. The rim seal foam pourer is used in one of the most common applications of protecting tank seal in vertical liquid storage tank with internal floating roof with low expansion foam system.
